WASHINGTON (RNS)—The latest in a long line of studies shows church attendance is good for your health, but some questions remain unanswered.

Published in May by researchers from Vanderbilt University, the study found middle-aged adults who attended religious services at least once in the past year were half as likely to die prematurely as those who didn’t.

Using data from a National Health and Nutrition Examination Survey collected by the Centers for Disease Control and Prevention, the study’s researchers examined 10 biological stress markers among 5,449 men and women aged 46 to 65. They then compared those markers with respondents’ self-reported religious service attendance and found a correlation between religious service attendance, lower stress and longevity.

The study adds to mounting scientific findings on the subject. A far larger study, of 74,534 women, published last year found that attending a religious service more than once per week was associated with 33 percent lower mortality compared with women who never attended religious services.

A documentary probing recent findings similar to these aired recently on many PBS stations—another sign of growing awareness of these studies’ significance, especially for older adults.

Questions without answers

But even as the studies pile up and the literature appears close to conclusive, many questions about the association between religious service attendance and health have yet to be answered.

For one, people attend religious services for all kinds of reasons. What is it about services that might impart better health? The prayers? The social connections? The coffee and cookies?

And does religious attendance—or something else—account for longevity? Could it be that people who attend church, synagogue or mosque happen to lead healthier lifestyles? Maybe they are on the whole predisposed to eat well, exercise regularly, engage in safe sex and drink alcohol in moderation?

How about people who bond over shared interests, such as knitting or poker, or devoted volunteers in literacy centers, or animal rescues? Has anyone studied whether these group members have lower mortality rates?

And finally, if, as so much evidence suggests, religious attendance is correlated with positive health outcomes, does that mean doctors should prescribe a weekly service to their patients?

A complex subject

“Religion is incredibly complex,” said Neal Krause, a retired professor of public health at the University of Michigan who is the lead investigator in a Landmark Spirituality and Health Survey. “To say, ‘Church attendance is good for your health’ does everything and nothing at the same time. The question is, ‘What exactly is going on here?’”

Krause points out not all religion is good for health. Religious devotion can lead to negative health outcomes if people are motivated to attend church out of guilt, for example, or feel God is punishing them through their illness. Indeed, studies have shown negative religious coping can cause spiritual distress that may lead to depression or early death.

But overall, researchers say, the field of spirituality and health—spanning numerous academic disciplines, including public health, nursing, social work, sociology, psychology and medicine—is improving as investigators dig deeper and try to ferret out causal relationships and eliminate other factors that may account for improved health outcomes.

No good studies on prayer and healing

One thing many researchers agree on: Studies analyzing whether prayer can heal illness have been shown to be methodologically, ethically and theologically flawed. Besides the question of whether prayer is an appropriate subject for scientific study and the fact it’s impossible to quantify the amount of prayer offered at a set time, there were a host of ethical considerations. For example: Is it ethical not to pray for someone, and does God heal some but not others?

The best of these studies showed prayers offered by strangers—sometimes called intercessory prayer—had no effect on the recovery of people undergoing surgery.

Religious attendance, however, is a subject researchers keep returning to. The question remains: What practical implications can be gleaned from these studies?

What is appropriate for physicians?

Many researchers agree that even if religious attendance does promote better health, it’s not appropriate for a physician to tell patients to go to church if they want to live longer—just as it wouldn’t be appropriate to tell patients they should get married because research shows married couples live longer.

“Physicians should know everything that has the potential to impact a patient’s well-being, whether it’s diet, social engagement, gun ownership or texting while driving,” said Richard Sloan, a biomedical researcher at Columbia University Medical Center. “My objection is when physicians try to persuade patients to engage in religious practices that are potentially coercive.”

For example, he said, it would be unethical for a doctor to try to convert patients to a particular faith or to initiate prayer with a patient.

Likewise, it’s not clear that going to church to improve the odds of survival is a good idea.

“I wouldn’t want a congregation of people there for health benefits,” said Daniel Sulmasy, a general internist and ethicist at Georgetown University and a former Franciscan friar. “In fact, we don’t know if people did it for that reason, rather than intrinsic reasons, that there would be a correlation.”

But some studies at the intersection of religion and health might help clinicians do a better job of caring for patients.

For example, studies have shown chaplain visits in hospital settings are associated with better health outcomes. This stands to reason, say researchers; when patients’ spiritual needs are met, they are more satisfied with their overall care. Another study suggested patients who take advantage of chaplain visits are more peaceful and feel more in control of their health.

More such research examining the efficacy of chaplaincy interventions are needed, said Christina Puchalski, professor of medicine and director of George Washington University’s Institute for Spirituality and Health.

“What can we do for the person that’s suffering?” Puchalski asked. “What are we doing so they aren’t alone? I try to accompany people in their suffering. That’s where we can all come together.”

And while researchers work to tease out the mediating factors in religious services that may hold the secret ingredient to health, there’s little question that religious groups have a lot going for them.

“Name a human institution that gives you a sense of community, hope, teaches you how to meditate, has all these kinds of disciplines associated with it,” Sulmasy said. “If it’s not a religion, it’s going to be close to a religion.”
